STRIPPING MACHINE.

Application filed April 22, 1221. serial No. 463,682.

To all whom t may concer/1t:

Be it known that l, CHARLES M. MoeNr, a citizen of the United States, and resident of the city of New York, borough of Manhattan, county of New York, and State of New York, have invented a new and lmproved Stripping Machine, of which the following is a full, clear, and exact description.

My invention relates to a stripping machine, and an article of manufacture which is capable of being produced by this machine.

It is a well appreciated fact, in connection with brushes, hat it has been necessary to elnploy a brush back, suitable members constituting bristles, and means for retaining the bristles in applied position with respect to the back. 'Considerable objection has arisen, more particularly with the latter means, in that the bristles were liable to become loosened.

Vith-this in view, a number of manufacturers have vulcanized or cemented. the bristles to the back, which has overcome this difliculty to a great extent. l'

Further, the cost of manufacturing` this latter type of brush, has been such that the construction has been inapplicable to brushes intended for ordinary uses, such as scrubbing,-etc., in that the retail price of the same would not be proportionate to the value of the article.

With this in mind, my present invention aims to provide a stripping machine which will be capable of producing such articles as brushes of any type, which shall incorporate the advantage of having their bristle elements virtually incapable of becoming accidentally removed from the member constituting the back of the same.

A further object of this invention is the construction of a stripping machine, as well as thel article of manufacture produced thereby, which machine will vbe practically automatic in operation, aside from 'the fact that it will be extremely silnple in construction, and capable of being manufactured at a nominal ligure.

Further objects of my invention will appear in the annexed specification and drawings. which latter illustrate one practical embodiment thereof, and in which;

Figure i is a side view of a machine enlbodying my improved construction.

Figure 2 is sectional view taken along the lines 2 2 and in the direction of the arrows indicated in Figure l.

Figure 3 is an enlarged sectional view of one of the frames utilized.

Figure 4 is a detail thereof.

Figure 5 illustrates the stripping element employed.

lligure 6 is a sectional view taken through the finished article produced by the machine, and

n igure 7 is a partly fragmentary plan view of one of the elements permitting of the semi-automtic operation of the machine.

Referring now more particularly to Figures 1 and 2 it will be seen that the reference numeral l() indicates base of any suitable construction which constitutes a rigid support for the machine, and to which a frame 11 is secured.

Mounted within the frame 11, and more particularly the longitudinally centrally entending members 12 thereof, is a stripping' plate 13 which is slide-.bly retained ill this position by any suitable means, such as that of having its outer edges attached to apex members leo-operating with a. corresponding groove in the inner facesrof the longitudinal lnelnbers 12.

The stripping plate preferably has a pair of backing sheets 14 secured to its side faces, and thesesheets retain teeth 15 in applied position upon the plate 18, and with aview of reciprocating the entire stripping element thus provided, it will be noted that l employ any suitable means such as a rotatable crank 16 having one of the ends of a pitman 17 secured to it, the opposite end thereof being rockingly attached as at 1S, to theV stripping plate lvthus permitting of the stripping element being moved longitudinal of the frame 11 upon the crank being rotated by means of the pulley 19.

Guide rails 2O are transversely mounted within the frame 11, and these guide rails serve to mount slidably arranged trays 21 positioned one to each side of the strippi member aforedescribed. Also, opgositely screw threaded b-ars 22 extend transversely of the frame il, and these bars project through correspondingly threaded cpenings in lugs 23 forming a part of each of the trays 2l so that upon the bars being rotated by any suitable means such as worms 24 forming parts of shafts 25, it will be obvious that the trays 21 will either be member. f

With a view now of providing means which will serve to permit of the elements to be operated upon being mounted within the trays, I employ clamping racks 26 each comprising a plurality of longitudinally eX- tending spaced parallel bars 27 secured together by means of transversely extending bars 9.3 which latter have their outer ends screw threaded to permit of screw threaded sleeve 29 being mounted thereon, which sleeves ma be rotated by means of handles 30 thus o viously varying the spaces between the bars 27.

Each of the trays 21 are formed with slots 31 in certain of their side edges, and adjacent. the inner ends of these slots, spring pressed latches 32 are slidably mounted. The clamping racks each carry pins capable of being accommodated within the slots 31, and sleeve lugs 34 are also secured to their lower edges and cooperate -with openings in the lower portions of the ytrays 31 lso that the clamping rack may be swung, and are retained in applied position with respect to the tray 21, with which it is associated, it being also obvious that the pins 33 will move. into the slots 31, and be retained in their proper position by means of the latch 32 so that one tray and clamping rack constitute in assembled position, a singleunit. y

Although my invention is not necessarily limited to use in this connection, it is primarily adapted to act upon blocks, sawed or otherwise formed from the trunk of a palmetto palm; The trunk of these trees, asis well known, consists of a Vmass of fibres, which. embody great vresistance qualities, the spaces between the bres being completely filled by a m'ass of fine particles in intimate contact with the fibres. In use, the clamping rack is primarily removed from the tray by retracting the latch 32, and in swinging the clamping arm outwardly, and subsequently lifting the same from the tray. A rotation of the sleeves 29 will permit of the bars 27 being spaced to the necessary eX- tent, ytoy allow of the blocks specified being arranged between their side faces. Subse- `quent to this a clamping of the bars by means of these sleeves may be effected, and obviouslyyany movment on the part of the blocks will be prevented.

The clamping racks are now re-applied to their respective 'trays and the machine is then ready for Operation.

Vith a view` of providing means which will not alone serve to rotate the shafts 25 synchronously, but which will also permit of a `semi-automatic operation of the entire vdevice, it will be noted reference being had toA Figure l that the pulley shaft serves to drive a supplemental shaft 35 by means of 1, primarily in the stripping element being reciprocated Aby means of the pitman 17. Consequently thesupplemental shaft 35 will also drive the clutch sleeve 37, which, meshing with theclutch of the gear `39 will impart rotation to bothof the shafts 25, and through the worms 24 tothe bars 22, this resulting in a feeding of the trays towards l a central point. i

Obviously the teeth 15 will gradually move to a greater depth into the blocks 4Q,

and will remove the mass of fine material from between the fibres thereof withoutin the slightest injuring the latter. Obviously this stripping of the mass from between the Fibres must cease at a point well in advance,

of the 'rear face ofthe blocks, and with a view of automatically permitting of this function being accomplished, it will` be seen, referencey being had to Figures 1 and 7, that one of the trays 21 carries a-lug` 43 which co-operating with a shifting fork 44 controlling a series of .linkage 45, will obviously result in this linkage being positively moved upon the tray 21 moving yto either of its extreme positions. A bell cra-nk 46 is secured to the outermost end ofthe linkage 45, and is rockingly mounted upon the base 10, said rocking being preferably limited by means of stops 47, it being also noted that the inner end of the bell crank is secured to the clutch sleeve 37. y

Thus upon the trays 21 having been fed in for a certain predetermined distance, permitting of the mass of fine material being removed from gthe fibres of the blocks42 to a desirable depth, the lug 43 will co-operate with the inner arm of the fork 44 and move the linkage 45, thus shifting the clutch sleeve 37, this latter movement vbeing preferably accelerated by means of a weight 48 affixed to the outer arm of the bell crank 46.

Assuming that through negligence, the machine was not stopped after a mass of 4AInaterial had been removed from between the fibres of the blocks, it will thus be seen that no harm might i-esult, in that the trays would continue to be fed outwardly, and inwardly until such time as the machine was brought to a stop, the stripping vaction always terminating at a predetermined depth.

Thus it will be seen that the objects set forth in the preamble of this specification have been accomplished, in that astripping machine of extremely simple construction, and eicient operation is primarily provided. Furthermore, brushes thus constructed will be found .to include one integral element provided by nature in that both the fibres and the mass of line material retained and constituting a backing plate, and securing element for the fibres form a single part of the trunk, the fibres constituting the bristles being merely produced by removing the mass of fine material to a predetermined depth.

Also it has been found that brushes constructed in this manner are not alone limited to use such as scrubbing etc. but that portions of the blocks constituting the backing plates may be polished and finished to an extent to produce an extremely pleasing article, susceptible to being used in anyassociation, it being also noted, in this connection that this article is capable of being produced at an extremely nominal figure.

Obviously numerous modiiications of structure might readily be resorted to without in the least departing from the spirit of my invention, which I claim as;
